Description
This proposal concerns elucidation of the fundamental chemical and electrochemical processes occurring in the operating air electrode of reversible Solid Oxide Cells (rSOC) constructed using novel, Cu-containing complex oxides with RE1-xAxM1-xCuxO3-δ (RE: selected rare-earth elements, A: selected alkaline-earth metals, M: selected 3d metals) chemical formula. Focus of the studies will concern identification and understanding of the principles governing the electrocatalytic activity toward the oxygen reduction and oxygen evolution reactions. Based on the research it will be possible to propose the optimized, chemically and thermomechanically stable Cu-based compounds, ensuring efficient operation of the air electrode in the fuel cell and electrolyzer modes at reduced temperatures, below 800 °C (with the aim of effective operation in the vicinity of 600 °C).
